If you thought SS was hard wait... Fish Wicks are not difficult at all, getting the coil around them is.
If I were new to RBA's I would rather practice with mesh first, get my coil and wick techniques mastered then venture into the world of ceramic wicks.
These are exceptionally fragile and you will need to purchase more than 3 to get one working.
A silica setup in a RBA will not give the same vape as mesh. The two are completely different, you don't require a Torch perse you can still achieve an oxidized wick with a lighter or on your gas stove.
